In a recent article Gensler (2003) has argued that little can be said about the ordering of bound person markers of the T(heme) and R(ecipient) relative to each other or relative to the verb stem apart from the fact that the outer markers are likely to be the result of a second-level cliticization process. We take issue with this claim and document that quite successful predictions with respect to the ordering of the T and R markers can be made on the basis of morphological alignment. Taking as our point of departure the typology of ditransitive alignment outlined in Haspelmath (2004; 2005), we show that the ordering patterns in which the R is placed closer to the verbal stem than the T are favoured in all relevant alignment types apart from the indirective, which exhibits a preference for positioning the T closer to the verbal stem than the R. These preferences for the ordering of the R and T are argued to relate directly to the frequency of use of the relative person forms and thus are seen as constituting yet another piece of evidence for the usage-based model of grammar being developed within the functional-cognitive typological paradigm (cf. e.g. Barlow & Kemmer 2000; Bybee & Hopper 2001; Tomasello 2003).
